Concepts & reference
Gates, operations, and the glossary
Short visual explainers for each gate (one interactive Bloch-sphere demo each), plus the operations reference and the glossary of quantum-computing terms.
Hadamard gate
Puts a qubit into superposition. The most-used gate in quantum computing.
Pauli-X gate
The quantum NOT. Flips |0⟩ ↔ |1⟩.
Pauli-Y gate
A 180° rotation about the y-axis with an added phase.
Pauli-Z gate
The phase flip. Invisible in the z-basis.
T gate
A 45° phase rotation. The third gate in the universal set.
CNOT gate
Two-qubit gate that creates entanglement. A quantum if-statement.
Quantum measurement
Collapses a qubit to one of two outcomes along the axis you pick.
Glossary
Plain-language definitions for the terms you keep running into.
Read the course. Then hold the qubits.
